Overview
- New intense strombolian explosions at the Voragine crater began on Sunday and were followed by renewed ash emissions from the North‑East crater, according to INGV field reports.
- INGV recorded a rise in volcanic tremor from medium to high with source centroids between the North‑East crater and Voragine at about 2,800–3,000 meters, and an increase in infrasound events centered at Voragine.
- A new effusive vent opened in the Valle del Bove at roughly 2,200–2,350 meters, producing lava flows and ash that are dispersing southeast from the summit area.
- The INGV VONA remains orange for aviation risk, and Catania airport operator SAC has partially closed airspace sectors and limited incoming flights, most recently allowing up to ten arrivals per hour in a reduced sector through 12:00 on 18 August.
- INGV teams are carrying out on‑site surveys to track lava‑flow fronts (the most advanced front sits near 1,395 meters) and authorities warn the situation is active and could prompt further operational or local restrictions.
